(1) An asteroid is moving along a straight line. A force acts alongthe displacement of the asteroid and slows it down. The asteroidhas a mass of 3.2 Ã 104 kg, and the force causes its speed tochange from 7700 to 5700 m/s. (a) What is the work done by theforce? (b) If the asteroid slows down over a distance of 2.2 Ã 106m determine the magnitude of the force.

(2) Rocket Man" has a propulsion unit strapped to his back. Hestarts from rest on the ground, fires the unit, and acceleratesstraight upward. At a height of 17 m, his speed is 4.9 m/s. Hismass, including the propulsion unit, has the approximately constantvalue of 131 kg. Find the work done by the force generated by thepropulsion unit.

Earth is rotating about the Sun in our solar system. The distance between the Earth and Sun
is 1.5 × 1011m. Consider the impact of an asteroid of mass 8.9 ×1015 kg and a speed of 90,000
km/h with respect to the Earth’s surface. The asteroid strikes the Earth at the equator as shown
in Figure. Consider the mass and radius of the Earth are ME = 5.97 × 1024 kg and RE = 6.38
×106 m, respectively. Assume that the axial and orbital axis of rotations are parallel to each
other.

(a) Calculate the axial and total angular momentum of the Earth. (4 marks)
(b) What is the change in the angular velocity of the Earth due to the collision? (6 marks)
(c) What is the maximum possible change in the length of a day due to the collision?
(3 marks)
(d) How much energy is needed to stop the Earth’s rotation about its axis after the collision?
(4 marks)
(e) What would be the moment of inertia of the Earth if the axis of rotation is parallelly
shifted so that it touches the equator?
